34+ Keto Enol Tautomerism Is Shown By Gif. Resonance requires that only electrons change positions. You may wish to review.
And the whole reason i show you this mechanism is, one, just to show you a mechanism that could happen with an aldehyde or a ketone. Studies show that the tautomerization process is significantly inhibited at ambient temperatures ( kt ≈ 10−6 m/s), and the half life of the enol form can. Tautomerism is for example relevant to the behavior of amino acids and nucleic acids, two of the fundamental building blocks of life.
Keto/enol tautomerism under acidic conditions.
Keto‑enol tautomerism was first introduced in section 9.4, in the discussion of the hydration of alkynes. Resonance requires that only electrons change positions. Tautomerism is the phenomenon that occurs in any reaction that simply involves the intramolecular transfer of a proton. To understand where an equilibrium lies, we must compare the relative stabilities of the products (enol) and reactants (carbonyl compound).
